durable construction by which the various operations can be performed rapidly and et` liciently. Another object is to provide an apparatus byrwhich theamount of liquid per 1o can is automatically measured, so that all cans of given size and shape will contain siib'stantialjl-ythe same amount. To these and the'r ends the invention comprises the novel features and 'combinations hereinafter described.

Incarrying out the invention in the preferred manner I providea pair of' three-way valves of thelrotary plug type, preferably combined in one structureand operated by a 2Q single handle.` The inlet port-of' one valve i is connected witha source of ether, while one outlet port is connected to an inlet or filling tube to` discharge` into the can and the other is connected with an overflow pipe for discharge` ofether from the can until the predetermined amount is left in the can. The otherf valve has its inlet port connected with a source of carbon dioxid, while one outlet Port is connected with theaforesaid overflow .n 3 0 pipe and the other isconnected with a pipe `for the carbon dio-Xid into the can. Meansare also provided for holding the can operative position with respect to the valves, so that by plfopermanipulation thereoi' theoperator can first fill the can or other receptacle with carbon. dioXidV to purge the saine of air, then 'fill the can with ether, driving out all the carbon dioxid, then admit carbon dioXid again to drive out a portion ofthe etherwand leave only'a predetermined quantity therein.

The embodiment outlined above is illustrated in the accompanying drawings, `in which fig, 1 is a sidelview of the complete appai Y ratus.`

view ofthe same with the upper and middle brackets, and the ether and carbon dioXid supply pipes, in section on line 4-4 of ig. 1. Figs. 5, 6 and 7 are diagrammatic views in horizontal section, showing the different positions of the valve in the lilling operation. ln these figures the upper sections are taken on line a-(t and the lower sections on line b-b of Fig. 3. n y

The standard 10, vertically adjustable in the base 117 has an upper bracket 12 provided with a clamping ring 13 in which the filling `valve 14 can be clamped by means of the binding bolt 15. The base also carries a vertically: movable stem-16 carrying a table 18 forthecan 19 which is to be filled.

The stem 16 and table 18 are raised by two pairs of toggles 20, 21, pivoted at the topto the head 22 of the stem 16 and at the bottom to the guide 24 on the base 11. The center jointsof the toggles are connected by contractile springs 25, 26, which urge the toggles toward straight position, thereby raising the stem and table, as will be readily understood. Between the bracket 12 and table 18 the standard is provided with an arm` 30 having in` its outer end a downwardly open socket l31 to receive the neck of the can 19 and having a yielding gasket-32 to make a gastightjoint with the edge of the neck when the can `is in filling position.

The valve 14 comprises `a casing 33 and a tapered plug 34 which can be rotated by a handleS. The `plug has an upper angular transverse passage 36, to cooperate with `an ether inlet or supply pipe 37 connected with the ether receptacle not'shown, an ether deliverypipe 38 for conveying ether into the Y can, and an overflow pipe 39 for carrying away ether expelled from the can, these three pipes being hermetically fitted to apertures in the valve casing. The plug also has a lower angular passage 4() to cooperate with a carbon dioXid supply `pipe 41 connected with the cylinder of carbon dioxid under pressure, not shown, a carbon dioXid delivery pipe 42 for conveying the gas to the can, and a carbon dioxid 'overflow or discharge pipe 43 for carrying away gas expelled from the can. `The pipes`41, 42,43 are hermetically fitted to suitable apertures in the valve casing, and in addition pipe 43 may be connected to pipe 39, as indicated. Pipes 38 and 42 extend into the socket 31 in arm 30 and are sealed in place.

The filling operation Will noW be readily understood.

The supply pipes 37, 41 being connected respectively to a source of ether and to a source of carbon dioxid (CO2) under suitable pressure, and the valve being in the off position, Fig. 5, the operator depresses the table 18, places a can thereon in position to receive the pipes 38 and 42, and then allows the table to rise. This causes the pipes 38 and 42 to enter can 19 and seals the neck of the latter by pressing it against the gasket 32. The operator novi7 gives the valve a quarter turn to the position represented in Fig.

" 6, in which the ether supply pipe 37 isstill closed but the CO2 pipe'41 is connected with pipe 42 through valve passage 40. Carbon dioxid then enters the can 19 in the form of a jet, strikes the bottom oftl the can and eX- pands radially, and rising in the can` drives air out ahead of it through pipe 38, valve passage 36, and pipe 39. It Will be understood that this operation is very rapid, so that only a momentary holding of the valve in the position of Fig. 5 is necessary. The valve is then turned a quarter of a revolution to the position of Fig. 7. Ether now enters the can through valve passage 36 and pipe 38, expelling the carbon dioXid through pipe 42, valve passage 40, pipe 43 and pipe 39. As soon as the rising ether reaches the pipe 42 it begins to rise therein and then issues through valve passage and pipe 39 into a suitable receptacle, not shown. The operator then knows that can 19 is filledwith ether and emptiedof carbon dioxid, whereupon he gives the valve a uarter turn back to the position of Fig. 6. arbon dioXid now enters by Way of passage 40 and pipe 42, and forces ether out through pipe 38, valve passage 36 and pipe 39, until the ether in can 19 has fallen to the bottom of pipe 38, after which carbon dioXid enters the latter pipe.

- When the flow of ether through pipe 39 ceases, the operator gives the valve a quarter turn back to the 0H position, Fig. 5, depresses the table 20, removes and seals can 19 or passes it on to another person for sealing,

- puts another can on the filling table, and the cycle described is then repeated.

It will be observed that the depth of the ether left in the can when it is removed for sealin depends upon the height of the bottom 0% thek pipe 38 above the bottom of the can when the neck of the latter is pressed up in the socket member 31. The latter may thus serve as a stop for the can. Hence if the cans are all of uniform size and shape the will'all have the same quantity of ether, wit the same volume of CO2 above. This is an the same is closed automatic measuring, the accuracy of which.

is virtually independent of the operators judgment. The operator can therefore Work rapidly, with the assurance that the machine is responsible for the accuracy of the measurements.

In the embodiment illustrated the amount of ether finally left in the can depends upon the size andshape of the can, and to vary the amount it is necessary to vary one or another of these factors, unless the length of' the pipe 38 is altered. It the height of the can is changedmaterially the standard 10 may be adjusted vertically to compensate for the change and keep the elongation and contraction of the springs approximately the same as before. The lifting effort of the springs depends upon their tension. The springs at one end are connected directly to the toggle pivots 45. At the other end they are connected to short rods 46 passing through the toggle pivots 47 and threaded into stop-nuts48, so that by adjusting. the latter the tension can be regulated. The upper position ofthe table 18 may be determined by an adjustable collar 49 encircling stem 16 below the base 11 and secured in adjusted position by a set screw 50.

It is to be understood that the invention is not limited to the specific construction herein illustrated and described but can be carried out in other Ways without departure from its spirit.
